Abstract

L'invention concerne un dispositif de commande d'aube à angle de calage variable pour compresseur de turbomachine, comportant une biellette (14), des moyens de fixation d'une première extrémité (14a) de la biellette sur un pivot (10) d'une aube à commander, et des moyens de liaison (18) entre une seconde extrémité (14b) de la biellette et un anneau de commande (16). La biellette (14) est de forme sensiblement cylindrique, sa première extrémité (14a) étant emmanchée dans un alésage du pivot (10) de l'aube. Le dispositif comporte en outre des moyens de pincement de la première extrémité (14a) de la biellette (14) dans l'alésage du pivot afin d'assurer sa fixation sur ledit pivot.The invention relates to a blade control device with variable pitch angle for a turbomachine compressor, comprising a link (14), means for fixing a first end (14a) of the link on a pivot (10) of a blade to be controlled, and connecting means (18) between a second end (14b) of the rod and a control ring (16). The rod (14) is substantially cylindrical in shape, its first end (14a) being fitted into a bore of the pivot (10) of the blade. The device further comprises means for clamping the first end (14a) of the rod (14) in the bore of the pivot to ensure its attachment to said pivot.
